STRAINING WIRE.

Patented Dec. 25, 1906.

Application filed January 23,1906- Serial No. 297,628.

To all whom it may concern.-

Be it known that I, WILLIAM NEPEAN- I'IUTOHISON, engineer, residing at57 Peckham road, Camberwell, London, England, have invented certain newand useful Improvements in Apparatus for Straining Wire, and I do herebydeclare the following to be a full, clear, and exact descri tion of theinvention, such as will enable OEIGIS skilled in the art to which itappertains to make and use the same.

The object of my invention is to provide a wire-straining device of suchkind that upon its application to a slack wire the wire is tightened bysimply rotating the device, which by reason of its formation, as hereinafter described, remains upon the wire so strained as a permanency,keeping the wire in a taut condition.

My invention, which possesses advantages over others now in use,comprises a straininglever and a block of metal, each of peculiar formand neither of which can be used alone.

The aforesaid block will hereinafter be termed the strainer, as thatword has been commonly applied to articles previously in vented in thesame class.

In order that my invention may be clearly understood, I will now proceedto describe same, reference being made to the accompanying drawings, inwhich like letters indicate like parts.

Figure 1 is a side view of the strainer. Fig. 2 is a plan view of thestrainer and the strainerbar, showing also the wire. Fig. 8 is aperspective view of the strainer-bar removed from the strainer.

In the drawings, A is the base of the strainer. This is preferably ofsemicircular section, but may be rectangular or otherwise.

The base A has a pillar or drum B, by preference centrally disposed, andthis pillar or drum B is bifurcated at its extremity, the two prongs Band B being a little spread at the side, and at the termination of eachprong on opposite sides is formed an overhanging point B and B,respectively. These I are with the object of preventing the wire Dslipping off the strainer.

The base A is provided with a hook C and l C on the left and right hand,respectively, the opening of the hook being the farthest from oropposite to the point of the stem- 1 prong to which it is nearest. Thehooks C and are to prevent the wire unwinding after straining.

The straining-lever is marked E and may be made of a strip of flat ironor steel. It is bent to the shape shown and handle E formed so that thestraining operation can be performed without the handles getting in theway of the wire strained.

Two clips E and E capable of renewal, are placed adjacent to the centerand at such distance that the strainer can be slipped between them, asshown.

In order to strain, tighten, and hold taut any slack wire, the straineris placed in positionbetween the handle-clips so that the wire passesbetween the strainer-prongs B and B By rotating the lever the wirebecomes strained u on the drum.

I/Vhen t 1e wire is sul'liciently taut, the hooks C and C are allowed toengage with the wire,

may be mentioned also that unless a lever be used it is next toimpossible to release the strainer when once in its position on the tautwire.

I claim In a wire-tightening device, the combination, with astrainer-bar provided with means for engaging the wire; of anoperating-lever having cranked handles at its ends, and two removableclips secured to the middle part of the said lever and holding the saidbar between them crosswise of the said lever.

In testimony whereof I aflix my signature in presence of two witnesses.
